MICHIGAN PAINTING Application filed March 26, 1928.

This invention relates to painting instruments and more particularly to striping instruments.

An object of the invention to provide a striping instrument having means for guiding the instrument with precision.

Another object of the invention is to provide a striping instrument having a plurality of guide members arranged to prevent disalinement of the instrument during the manipulation thereof.

Another object of the invention is to provide a striping instrument having a plurality of rotatable guide members arranged on one side of the instrument in different planes with respect to each other, so that any liability of the instrument becoming disalined during the use thereof is avoided.

A further object of the invention is to provide a striping instrument having a contaliner readily adjustable to various positions, according to the plan-e in which the instrument is to be used.

A further object of the invention is to provide a striping instrument having a nozzle provided with a web arranged as a support and a guiding means.

A still further object of the invention is to provide a striping instrument having a flexible pivoted handle formed to fit in the hand of an operator between the thumb and forefinger and provided with suitable finger grips whereby the instrument may be readily held in engagement with the surface to be striped without liability of displacement or tiring the hand of the operator.

A still further object of the invention is to provide a striping instrument having a body portion with a plurality of rotatable guides and a gear pump adapted to be operated by one of the guides, a container connected with the intake of the gear pump, a nozzle connected with the outlet of the pump, the guides and nozzle being so positioned with respect to each other that tilting of the instrument is avoided.

Other objects of the invention will appear from the following description taken in connection with the drawings which form a part of this specification, and in which:

EEICIEYZGAN, A CORPGBATION' OF INSTRUMENT Serial No. 284,761.

Figure 1 is a top plan View of the instru ment,

Figure 2 is a side elevation with the container and handle broken away and the face plate removed,

Figure 3 is a similar view with the handle removed and parts broken away to better illustrate the nozzle and its connection with the pump mechanism, and

Figure a is a sectional view taken substantially on line 4il-, Fig. 3.

Referring by numerals to the drawing, 10 represents a body portion comprising a rectangular solid having formed on each end thereof and normal thereto a lug 11 apertured as indicated at 12 to receive a pin 13. The pins 13 provide a pivotal support for a flexible handle 14. As shown, the handle is provided with apertures 15 which engage the pins 13 and the free ends of the handle are curved to provide finger grips 16. This handle is sufficiently flexible to be easily connected. or disconnected from the instrument ant is formed to ft between the thumb and forefinger of the hand of an operator so that the instrument can be manipulated without danger of disalinement or fatigue to the hand of the operator.

The body portion 10 has arranged therein in spaced relation with respect to each other and projecting normal from one side there of shafts 17 and 18. The shaft 17 has secured thereon a roller or guide member 19, provided with a concave face or periphery 20 adapted to fit over a moulding or bead, and the shaft 18 has journaled thereon a roller 21 having opposed flanges, one of which is beveled as indicated at 22 to engage the side of a moulding and the other has an increased diameter and is rounded as indicated at 23 to engage the surface at the base of the mouldmg.

The body portion 10 has a tapering bore 24: in which is positioned a plug 25, the plug being secured therein by means of a nut 26 threaded upon the smaller end thereof. The plug 25 is axially bored as indicated at 27 and h as circumferential groove 28 connected with the axial bore by a plurality of radial bores 29. The larger end of the plug 25 has a head 30 provided with a bore. 31 communicating with the axial bore 27. The bore 31 is adapted to receive the discharge end 32 of a container 33, the container being pro vided with a cap 34 secured on the container by means of a bayonet joint 35. By reason of this structure the container 33 may be moved from side to side or to any position which may be found. desirable and advantageous in feeding fluid from the container by gravity to a pumping mechanism to be hereinafter described.

The shaft 17 projects through and beyond the body portion 10 and has keyed thereon a gear 36 flush against the body portion 10. This gear has in mesh therewith a corresponding gear 37. The gear 37 s not ournaled, but notwithstanding it rotates on its own aXis and is held in mesh with the gear 36 by means which will hereinafter appear. Arranged in the body of the instrument above and between the gears 36 and 37 is a passage 38 communicating with the circumferential groove 28 in the plug 25 and arranged in the body portion below and between the gears 36 and 3? is a passage 39 communicating with a transverse bore 40 which in turn communicates by a passage 41 with a nozzle 42.

Fitted over the intermeshing gears 36 and 37 is a plate 43 having arranged therein overlapping transverse bores 44 and 45. The bores 44 and 45 serve to retain the gears and 37 in position and these bores cooperate with the gears 36 and 37 to provide a suitable pumping means from the passage 38 to the passage 39 and hence from the container 33 to the nozzle 42. The plate is substantially the same thickness as the gears 36 and 37. If anything, the gears would be .001 or .002 of an inch thinner so that the gears might rotate within the respective bores without danger of binding and yet suifciently tight to prevent any possibility of leakage. The plate 43 and the gears are covered and secured in place by a face plate 46 and suitable screws 47 threaded into the body portion 10, one of the screws 47 being threaded into the end of the bore 40.

The nozzle 42 is inclined to the bottom of the body 10 and has formed thereon a web 48 arranged adjacent the outlet of the nozzle and to project in the path thereof when the instrument is manipulated to paint stripe. The web 48 is thin yet sufficiently rigid to maintain its proper relation to the nozzle; it is of sufficient proportion to span an opening or depression of small dimension and its free end is curved upwardly in order that the nozzle will ride freely over the small openings, depressions and obstructions.

In operation, the container 33 is filled with liquid paint and the instrument adjusted to the work to be performed. In adjusting the instrument to the work. the actuating roller and guide 19 bears on the top of a moulding and the roller 21 engages the moulding on one side and the base thereof on the other side. The bearing points of the rollers are in different planes with respect to each other and with respect to the nozzle, hence, any possibility of the instrument wabbling is avoided, besides, an efficient guiding means is provided.

The instrument is held firmly in position by means of the handle and the handle is provided with finger grips which materially aid the operator in keeping the rollers 19 and in proper relation to the moulding. As the instrument is moved over the surface to be striped the roller 19 drives the shaft 1':'. This shaft carries the gear 36 which meshes with the gear 3?, hence, the gears 36 and 37 are driven in opposite directions and accordingly draw the paint from the passage 38"and force it to and through the passages 39 and 40 to and through the nozzle 42. In other words, the gears 36 and 37 function as a gear pump for pumping paint from the container to and through the nozzle.

Although this invention has been described in connection with certain specific embodiments, the principles involved are susceptible of numerous other applications that will readily occur to persons skilled in the art.
